Interesting to monitor emission event periodicity. The proposed period was 30 days, so this is confirming my analysis... Also to be noted, in 2010 a sudden increase of emission in one day... rare event ?

oui,
bravo Valérie, bonne pioche. Je l'avais faites en aout 2012, elle venait de passer en absorption. Et cette année je l'ai oublié...
A mettre dans ma todo liste.
Also to be noted, in 2010 a sudden increase of emission in one day... rare event ?
Pas de trace de cette évènement dans la base BESS... y aurait il une base de spectres cachés

yes,
Congratulations Valerie, good pick. I had made in August 2012, it came to pass in absorption. And this year I forgot ...
To put it in my todo list.
Also to be noted, in 2010 a sudden increase of emission in one day... rare event ?
No trace of this event in the database BESS ... would there be a hidden base spectra

Non, a priori les spectres sont tous des requetes VO sur BeSS... pas de base cachée

Vu: le 28/09/2010 par christian le pic Ha est à 2,6 aors qu'il y a une belle série à 1.6
Super ton outil de comparaison car la présentation des spectres sous arasbeam est trompeuse
